Background technology
Casting is a kind of ancient manufacture method, and along with the development of industrial technology, the quality of casting heavy castings directly affects
The quality of product, therefore, be cast in machinery manufacturing industry and occupy an important position, the development of foundry engieering the most rapidly, method
Orchid is again ring flange or bead, is interconnective part between pipe and pipe, can be used for the connection between pipe end, it is also possible to
On equipment is imported and exported, the connection between two preparations, for the casting of above-mentioned ring flange, is first for this ring flange
The casting of blank, the material of general ring flange blank is aluminium alloy, and the casting mould of front main employing integral concave mould manufactures
Ring flange blank, can guarantee that the surface quality of squeeze casting, utilizes cope match-plate pattern lever and lower push rod discharging, and active force is uniformly put down
Surely, but there is tissue looseness, the defect such as pore, trachoma, and existing forging processing method manufactures flange, although the method produced
Blue quality is preferable, and interior tissue is uniform, there is not the pore in foundry goods, the injurous defect such as is mingled with, but the equipment of production is complicated, right
Quality requirements of raw materials is high, and utilization rate of raw materials is relatively low, and waste is serious, and production cost is higher, and current casting technique is typically wrapped
Including moulding, cast, cooling and knockout, molding sand effect in Foundry Production is particularly important, and common molding sand is mainly by roughing sand, viscous
Upper class binding agent, water and coal dust etc. form, and it tends not to well have the above-mentioned requirement to molding sand, because of molding sand
Poor quality and the casting wasted product that causes accounts for the 30～50% of the total waste product of foundry goods, the finished product cast hardness made is inadequate, not only
Casting process is more, affects production capacity, and the precision of foundry goods cannot be effectively ensured simultaneously, and percent defective is higher, therefore designs one
Operation is reasonable, save material, pour into a mould uniform, simple to operate, working stability, production efficiency height, conforming product rate height, molding matter
Measured flange casting technique is necessary, for improving the production efficiency of flange and having important work service life
With.
Summary of the invention
The present invention provide for overcoming the deficiencies in the prior art a kind of operation rationally, save material, pour into a mould uniformly, operation
